Xavier had $3.60 less than Wesley. After Xavier gave $2.10 to Wesley, Wesley would have four times as much money as Xavier. How much money had Wesley at first?
| |
Wesley |
Xavier |
| Before |
4 u - $2.10 |
1 u + $2.10 |
| Change |
+ $2.10 |
- $2.10 |
| After |
4 u |
1 u |
Xavier had $3.60 less than Wesley. If another $3.60 was given to Xavier, Wesley and Xavier would have the same amount at first.
4 u - 2.10 = 1 u + 2.10 + 3.60
4 u - 1 u = 2.10 + 3.60 + 2.10
3 u = 7.80
1 u = 7.80 ÷ 3 = 2.60
Amount that Wesley had at first
= 4 u - 2.10
= 4 x 2.60 + 2.10
= 10.40 + 2.10
= $12.50
Answer(s): $12.50
